The rules outline building the best Lewis dot structure, calculating steric number from bonded atoms and lone pairs, and arranging groups as far apart as possible. Lone pairs are emphasized as “FAT,” which are ignored only for geometry deduction. The notes give guidance on VSEPR’s strengths for octets and expanded octets, plus its limitation for transition metal complexes, and provide geometry examples such as linear, bent, trigonal planar, trigonal pyramidal, T-shaped, and tetrahedral.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":20,"@type":76,"position":81},"https://docshare.wps.com/document/exam/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/valence-shell-electron-pair-repulsion-theory-vsepr-reading/664703/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/valence-shell-electron-pair-repulsion-theory-vsepr-reading/664703.png","ImageObject",300,407,{"name":92,"@type":93},"fresh2021","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-29",true,{"@type":102,"interactionType":103,"userInteractionCount":14},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What
